For your consideration is this early Mexican donkey or horse pin. It is pre 1945. It is marked Mexico Silver - an earlier mark and has tested as sterling silver. It has another mark - some type of bird or animal as shown - not the eagle and I believe it is a maker but I could not locate it. It has the older style pin back with a c closure. The pin is puffed and has nice dimension.
It measures 2 and 1/4 inches head to tail by 1 and 1/4 inch head to front feet.
It is in great functioning vintage condition A few light scratches. Great patina. There is a hole in the back - not damage - part of the making.
